« on: October 16, 2018, 11:17:02 AM »
Worldwide federation of national standards bodies from nearly 140 countries.

 Established in 1947 to promote development of standardization of related activities in the world.

Mission is to facilitate the international exchange of goods and services and to develop cooperation in the sphere of intellectual, scientific, technological and economic activity

ISO publishes various international agreements as international standards.

ISO sets standards for many diversified field like information, textile, packaging, distribution of goods, energy production and utilization.

International Standards / Benefits of Standards
« on: October 16, 2018, 11:15:32 AM »
Standards facilitate communication and prevent misunderstanding

Standards make parts interchangeability possible and as a result mass production is possible

Standards can be used in marketing strategy to promote purchase of products that meet nationally recognized requirements, especially, when conformance is backed by a certain program.

Standards reduce cost and save money.

International Standards / Standards
« on: October 16, 2018, 11:14:51 AM »
Something that is established by authority, custom or general consent as a model or example to be followed.

Something established for use as a rule or basis of comparison in measuring or judging capacity, quantity, content, extent, value, quality etc.

The type, model or example commonly or generally accepted adhered to; criterion set for usage or practice.

According to ISO, standards are documented agreements containing technical specifications or other precise criteria to be used consistently as rules, guidelines or definitions of characteristics to ensure that materials, products, processes and services are fit for their purpose.

Textile Engineering / Benefits of Installing Apparel CAD System
« on: April 28, 2018, 07:19:01 PM »
By installing CAD software, you can be benefited in the following areas.

1. Eliminate manual steps in the design process. You can reduce manpower and improve the performance of the pattern making department.

2. Draft the garment pattern from scratch. Drafting a 2D pattern in the computer can be done by using CAD tools provided by the CAD provider.

3. Digitize existing hard-copy patterns. You might have made the paper patterns which is ready with you and approved by the buyer. You can digitize those hard-copy patterns in the CAD and store digitally.

4. Edit and finalize existing digital patterns easily. Pattern editing, pattern grading, and checking of the digital patterns can be electronically.

5. Store and restore digital patterns easily. You can save your designs (patterns) developed in the CAD and easily restore when you need. Copy and paste of the existing pattern can be done.

6. Visualize measurements of different styles and gain control of internal features such as notches, buttons, and drill holes.

7. Walk a pattern while you correct the shape, add or adjust details, and import patterns with every layer intact.

8. Darts, seam allowance, special corners, advanced measurement techniques, pleats, curves, and facings, are all fitted to trade, to meet the needs of customers across a wide range of product and style types.

Textile Engineering / 5 Reasons Why Apparel Fit Samples Are Rejected
« on: April 28, 2018, 07:17:49 PM »
#1. Poor workmanship: The workmanship done by the tailor is not up to the mark or not matching with the buyer specification of workmanship.

#2. Lack of understanding between the buyer and buying house: Sometimes the sample development team (either in the buying house or in a factory) starts developing fit sample without understanding the buyer's requirement completely. Sometimes merchandiser or the sampling technician don't understand the specification and develop the same based on their own understanding. As a result, the sample doesn't meet the buyer requirement.

#3. Non-availability of the actual trims and fabrics: Unavailability of actual trims and fabric cause the delay in sampling approval process. Even, the factory may develop the sample with the existing matching fabric quality and trims. This exercise may not meet the buyer's requirements.

#4. Late comments from the buyer: A buying house or a supplier does not always do the delay. It is also observed that buying houses or the supplier factories get buyer comment later than the scheduled time.

#5. There is no defined checklist from buyer's end:  In every submission, different comments are received from the buyer on the fit sample. The comment that can be given on the first submission, comes in the following submission. This leads the further need of sample development and sample correction.

In case you are facing the similar challenges in sample approval delay and sample failure in different stages of sample development, you need to find the root cause for this. and take action according to the root cause. Prepare standard operating procedures for sample development for fit sampling as well as other samplings. Buyer to buyer garment sample submission and approval criteria might be different. But if you know the primary reasons for sample rejection, you can deal with some variations.
