To supply fabrics that perform as promised, match approved standards in every lot and arrive with the testing and compliance records our customers need.
Who We Are
United Works Grass is a textile manufacturer supplying fabrics and finished goods to apparel brands, uniform programs and industrial buyers across and international markets. Our operation covers yarn sourcing, knitting and weaving, dyeing, finishing and inspection, with cut-and-sew available for select programs. Technical staff develop constructions to match your hand feel, weight and performance targets, and our laboratory verifies the result against recognized test methods. Customers value our consistent color matching, honest lead time commitments and the traceability we maintain from fiber source to shipped roll.
Textile buyers face long supply chains and plenty of surprises, so United Works Grass built its business around predictability. We hold approved color standards, document every recipe and keep a library of tested constructions that shorten development for returning customers. Our planners work with you months ahead of delivery to line up yarn, dye capacity and finishing slots. That discipline allows us to support both seasonal fashion and steady replenishment programs, with the same attention to quality on a small development order as on a full production run.
Track Record
Projects & Case Studies
Uniforms & WorkwearA uniform company needed durable twill with flame retardant and colorfast properties for a multi-year program. We established controlled color standards, scheduled quarterly production slots and delivered consistent fabric with every lot documented.
View Details
Home & FurnitureWe developed a woven upholstery range tested for abrasion cycles, seam strength and lightfastness. Samples and swatch books were delivered ahead of the customer trade show, and bulk production followed against an agreed schedule.
View Details
Technical TextilesAn industrial equipment maker required a precise woven media with controlled air permeability. Our team matched yarn and density to the specification, verified results in testing, and set up dependable supply for ongoing production.
View Details
ApparelWe developed a moisture-managing knit family in multiple weights and colorways, tested for shrinkage and pilling after repeated laundering. The collection moved from development to bulk within a single season while holding consistent shade across lots.
View DetailsOur Mission
To supply fabrics that perform as promised, match approved standards in every lot and arrive with the testing and compliance records our customers need.
Compliance
Sampling is supported, including for small development runs.
Send us your brief and United Works Grass will return a development plan with a proposed construction, sampling timeline and testing scope.
Every lot is tested for strength, shrinkage, colorfastness and chemical compliance, with documentation available to support your retailer requirements and customer audits.
Our Process
We review your reference fabric or design brief, target weight, composition, performance requirements and end use, then confirm the specification in writing.
Strike-offs, lab dips and test results are submitted for your approval. Adjustments are tracked until the final construction and color are signed off.
Approved specifications move to yarn procurement, knitting or weaving, dyeing and finishing, with in-process checks at each stage and a published production calendar.
Finished rolls are graded, tested and documented before packing. Shipments leave with the paperwork, labeling and tracking your receiving team needs.
Our Services
Softening, wrinkle resistance, moisture management, durable water repellency, antimicrobial and flame retardant finishes applied under controlled conditions. Each finish is selected for chemistry compliance and wash durability, and we test performance after laundering, not just on the fresh fabric.

Jersey, rib, interlock, fleece, pique and performance knits produced in a range of weights and fibers, including cotton, polyester, blends and elastane constructions. We develop to your hand feel and stretch recovery targets, test dimensional stability and shrinkage, and document the final construction so reorders run identically.

Our Advantages
Early forecasting and dedicated production slots help us hold lead times, even through seasonal peaks when mills tend to run late.
Technical staff translate your reference fabric into a manufacturable construction and offer practical advice on yarn, structure and cost.
Dyes, auxiliaries and finishes are managed against restricted substance lists, helping your product meet retailer and market requirements.
Strength, shrinkage, pilling and colorfastness are verified on site before shipment, so surprises are caught in our building, not in your warehouse.
Approved shades are stored with recipes and digital readings. Repeat orders are measured against the same references, keeping color consistent across seasons.
Yarn lots, dye batches and finishing records are linked to every roll. If a question arises, we can identify what went into the fabric and when.
New constructions get technical input and sampling rather than a quote and a shrug, and successful trials are documented so they can be repeated.
Yarn inputs are recorded through every process, so a question about a finished roll can be answered back to the fibre it was made from.
Restricted substance requirements differ by market and move. We confirm the rules for where you sell rather than for where we manufacture.

Client Feedback
Shade consistency used to be our biggest headache. Since moving this program to their mill, color approvals take one round instead of three, and garments from different lots finally match on the rack.
They took a vague reference swatch and turned it into a documented construction we could reorder with confidence. Their testing reports have also saved us real time with our retail compliance team.
Reliability is what we value. Delivery dates hold, paperwork is correct and when a lot misses spec, they tell us first and fix it quickly.

Questions & Answers
Minimums depend on construction, color and finishing. Stocked greige and library colors can ship in smaller quantities, while custom developments usually require a dyeing or weaving minimum. Share your target quantities and we will propose the most practical option.
Yes. Send a swatch or a reference garment and our technical team will analyze composition, construction and weight. We then propose a close match, submit strike-offs and lab dips and refine until you approve the specification.
We manage dyes and finishes against widely used restricted substance lists and can provide test reports from accredited laboratories for specific programs. OEKO-TEX aligned production is available for products requiring it.
Every shade has a stored recipe and digital standard. Production lots are measured with a spectrophotometer and compared against approved tolerances before release, and we retain reference samples for future comparisons.
For custom constructions, we suggest starting development at least one season ahead. Replenishment programs benefit from rolling forecasts, which let us reserve yarn and dyeing capacity and keep delivery dates dependable.
Yes. We provide development, sampling, production, labeling and packing to your retailer guidelines. A single point of contact coordinates the program, which reduces handoffs between fabric supply and finished goods.

United Works Grass is committed to making cendravolta.com usable by as many people as possible, including people who use assistive technology. This statement explains the measures we have taken and how to report a problem.
We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA as a target standard. Accessibility is treated as an ongoing obligation rather than a one-time project, and we review the site when we make significant changes to its structure or content.
Semantic HTML structure with a single main landmark, logical heading order and descriptive page titles, so screen reader users can navigate by structure.
A visible skip-to-content link, keyboard-operable navigation and menus, and focus styles that remain visible when navigating without a mouse.
Text and interface colors checked for contrast against their backgrounds, layouts that reflow at narrow widths and support browser text resizing without loss of content, and descriptive alternative text or accessible labels for images and icons that carry meaning.
Form fields with programmatically associated labels, required fields identified in text rather than by color alone, and link text that makes sense out of context.
Some decorative illustrations are presented without detailed descriptions because they convey no information beyond the surrounding text. Documents published in formats such as PDF may not meet the same standard as the website itself; we will provide an accessible alternative on request.
This website is designed to work with current versions of major browsers on desktop and mobile, used together with the assistive technologies available on those platforms. It may not perform as expected in browsers that are no longer supported by their vendor.
If you encounter a barrier on this website, or need information from it in an alternative format such as large print, plain text or a document read aloud, contact us at support@cendravolta.com or +31 38 385 2170.

We aim to acknowledge accessibility reports within five business days and will tell you what we intend to do and when. If an immediate fix is not possible, we will provide the information you needed by another means.
If you are not satisfied with our response, you may escalate the matter to the body responsible for accessibility enforcement in your jurisdiction. This statement is reviewed periodically and whenever the website undergoes substantial change.
